# Phoenix MCP Gateway: full tool reference

> One metered MCP endpoint in front of 16 MCP servers wrapping free and freemium APIs, exposing 139 tools. Each tools/call costs $0.0001 (100 micro-USD) from prepaid credits; discovery is free.

Connect over MCP Streamable HTTP to `https://gateway.mcpharbor.dev/mcp` with the header `Authorization: Bearer <your gateway API key>`. Supported protocol versions: 2026-07-28 (modern, stateless) and 2025-11-25, 2025-06-18, 2025-03-26 (legacy, `initialize` handshake). Tool names are namespaced by server, for example `arxiv__arxiv_get_metadata`. Read [agent.txt](https://gateway.mcpharbor.dev/agent.txt) before your first paid call.

Every tool listed here is routable right now. This file is generated from the catalog,
so a tool that is delisted for compliance reasons vanishes from it at the same moment.

## Start here

- [agent.txt](https://gateway.mcpharbor.dev/agent.txt): How to authenticate, what a call costs, which failures are safe to retry, and how to handle 402 and 429.
- [skill.txt](https://gateway.mcpharbor.dev/skill.txt): Task recipes that chain tools across servers, with the cost of each.
- [llms-full.txt](https://gateway.mcpharbor.dev/llms-full.txt): Every routable tool with its parameters, price and attribution.
- [server.json](https://gateway.mcpharbor.dev/server.json): Registry-format description of this gateway.
- [Registry API](https://gateway.mcpharbor.dev/v0.1/servers): Cursor-paginated catalog of every routable server.

## Pricing

- $0.0001 (100 micro-USD) per tool call.
- Billed on: each tools/call that reaches the upstream and returns a result.
- Free: server/discover, tools/list, registry endpoints, docs files.
- Payment: prepaid credits, drawn down per call. A call your balance cannot cover is refused with HTTP 402 before any upstream is contacted.
- A charged call that then fails upstream is refunded automatically.
- Retries are ordinary calls. There is no client idempotency key, so repeating a request that was already charged buys a second call - see [agent.txt](https://gateway.mcpharbor.dev/agent.txt), section 7.

- `endpoint` (string, required): Endpoint path returned by treasury_list_datasets (e.g., "/v2/accounting/od/debt_to_penny"). Include the leading slash.
- `fields` (array, optional): Fields to return. Omit to return all fields. Specify field names exactly as listed by treasury_list_datasets — a typo causes a 400.
